WILLIAM E. SCHNEIDER AND GUS E. VOELKSEN, or DA'zEY, NORTH DAKOTA;

RUG-IBEATER.

Application filed'March 8, 1918.

To all whom it may concern:

Be it known that we, WViLLiAM E. SCHNEI- DER and GUs E. VOELKSEN, citizens of the United States, residing at Dazey, in the county of Barnes and State of North Dakota, have invented certain useful Improvements in Rug-Beaters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention has reference generally to improvements in that class of inventions known as brushing and scrubbing and more particularly relates to an automatic rug beater.

As the primary aim and object, this invention contemplates the provision of novel beating means operatively mounted 'on a main supporting means and arranged upon opposite sides of a rug or carpet supported between the beating means so as to alternately strike the rug on opposite sides thereof as it is being drawn between the beating means.

It is an additional and equally important object of this invention to provide movable rug supporting means for carrying the rug or carpet between the beating arms when they are in actuation so as not to strike the rug continually in the same place and consequently insure of an effective cleaning of the rug.

More particularly, the present invention embraces the provision of novel means operably mounted in the main supporting means cooperating with the resiliently mounted beater arms for normally holding them in spaced relation with each other yet permitting of the arms to alternately move upwardly and'strike the rug positioned therebetween.

As an additional object this invention includes the provision of novel feeding means operatively mounted on the actuating means of the beating arms for feeding the rug supporting cable so that the rug will be moved while the beating arms are in actuation.

As a further aim, the invention consists in the provision of improved means for properly tensioning the rug supporting cable.

A more specific obj set of this invention includes the improved construction of the supporting means, as well as the improved rollers on the arms for cooperating with the notched disk for producing movement of the arms.

Among the other aims and objects of this Specification of Letters Patent.

Patented June 3, 1919.

Serial No. 221,190.

invention may be recited the provision of a device of this character mentioned with a view to compactness, in which the number of parts are few, the construction simple, the cost of production low and the efficiency high.

The invention is clearly illustrated in the accompanying drawings, in which Figure is a side elevation thereof; Y I Fig. 2 is a top plan view of Fig. 1;

Fig. 3 is an end elevation of the invention;

Fig. 4 is a transverse section taken on line H of Fig. 1 in the direction in which the arrows point;

Fig. '5 is a perspectivedetail of the feeding means for the rug supporting. cable;

Fig. 6 is an enlarged fragmentary sectional detail of the means for mounting the cam.

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings there is provided a pair of standards 1 and 2, the lower ends of" which are connected to the bases 3 the latter having feet 4: depending therefrom. A connecting base plate 5 has its respective ends connectedto the under surfaces of the bases to hold them in spaced parallel relation with respect to each other, while a cross bar 6 has its respective ends suitably connected in thestandards above the bases while braces 7 have their respective ends connected to the cross bar 6 for assuring of a rigid relation between the parts.

With a view toward providing a rug beating means there is employed a pair of complemental beating arms indicated in their entirety by the numeral 8. The l'owerends of the arms are pivotally connected upon opposite marginal edges of the connecting base plate 5 preferably by means of hinges 9. These lower ends of the arms are formed of suitable metal as indicated by the numeral 10 while the upper portions thereof are bent outwardly at substantially obtuse angles as indicated by the numeral 11. The upper or beating ends of the arms are formed of pieces of wire and shaped to provide the outline of a paddle 12. I

Suitable resilient means such as coiled springs 13 have their respective ends each connected to one side of the cross bar 6 and .11

tov the lower end of the adjacent beating arms. 'The tension of these springs is such as to normally hold the arms in closearelation with each other in such a manner that the angularly bent portions of the lower ends as well as the paddle shaped upper ends are arranged in spaced parallel relation with each other, while the extreme lower ends diverge toward their pivot points.

Cooperating with the resilient means is the actuating means which in the present instance consist of a shaft 14:, the respective ends of which are journaled in a bearing 15 mounted in the standard 2 and in another bearing 16 mounted on the cross bar 3 thus disposing the shaft above the cross bar. A disk 17 is carried by the outer end of the shaft and is provided on its periphery with a notch 18. This disk is disposed transversely between the adjacent faces of the angularly bent ends of the beating arms and incidentally cooperates with rollers 19 journaled on the inner faces of the angularly bent portions 11 on the lower ends of the arms. The springs 13 of course hold the rollers in yielding engagement with the periphery of the disk. The outer end of the shaft may be, and preferably is, squared, as indicated by the numeral 20 to removably receive the crank handle 21. WVhen it is rotated, the shaft will be rotated so that when one of the rollers alines with the notch, it will be forced into the notch, owing to the tension of the adjacent resilient spring 13, which action causes the paddle shaped end 12 on the beating arm to [move inwardly and strike the adjacent face of a rug not shown which is adapted to be supported between the arms. By further rotating the shaft, the opposite roller will move into the disk so that the adjacent beating arm will be correspondingly actuated. Of course, the continued rotation of the shaft produces an alternate actuation of the beating arms.

As intimated, improved rug supporting means have been provided. In reducing this feature of the invention to practice, pulley wheels 22 are mounted adjacent the upper and lower ends of each of the standards, while an endless rug supporting cable 23 is trained thereabout. The cable is also trained about a large pulley wheel 24 carried by a shaft 25, the respective ends of which are mounted in brackets 26 on the upper base plate 5.

WVith a view toward providing improved tensioning means for the cable, a threaded shank 27 is mounted 'in an opening 28 in the base 3 which supports the standard 1 and is adjustably engaged by a nut 29 having a handle 30 thereon which serves as a means for adjusting the shank with respect to the base. The outer end of the shank is forked as indicated by the numeral 31 while a pulley wheel 32 is journaled in the fork. The cable 23 is jourbeappreciated that by adjusting the shank 27 with respect to the base, the tension on all the pulley wheels will be consequently controlled. In addition it will be understood that by this tensioning arrangement,

the portion of the cable 35 between the two standards is taut so as to support the rug not shown as it is being moved therewith. i

For the purpose of providing improved means for feeding the rug supporting means so that the rug supporting means will be actuated simultaneously with the actuation of the beating arms, a ratchet wheel 36 is mounted on the shaft 25 made rigid with the large pulley wheel 2%. Cooperating with the ratchet wheel 36 is a bent engaging end 37 of a pawl 38, the inner end of which is enlarged and provided with an opening 39. The opening in the pawl is disposed about a disk 40 eccentrically connected to the shaft 1% and rotatable therewith. Ribs al are provided on both the side edges of the periphery of the disk 40 and are in turn arranged in spaced relation with the sides of the pawl to permit of a. slight loose movement between the pawl and the disk for the purpose that will presently be appreciated. Suitable resilient means such as a coil spring 42 has its respective ends connected to the'pawl and to the cross bar so as to yieldably hold the bent end of the pawl in engagement with the teeth of the ratchet wheel. By this arrangementit will be appreciated that upon rotation of the shaft, by reason of the relation between the pawl and the eccentrical disk, the pawl will be alternately moved up and down in a vertical plane and inasmuch as the spring -1 yieldably holds the engaging end 37 of the pawl in engagement with the teeth of the ratchet wheel, the latter will be rotated step by step and thereby act as a feeding means.

In use, assuming that a rug is over the portion 35 of the cable, to beat and clean this rug it is only necessary to rotate the shaft 14 which consequently rotates the notched disk 17. By reason of the fact that the arms are tensioned by the springs 13 so as to be normally drawn toward each other, the rollers riding on the periphery of the notched disk 17 will be pushed into the notch, thus imparting a corresponding motion to the paddle shaped end 12'of each arm enabling the arms to alternately strike the rug not shown upon alternate sides thereof. During this actuation, by reason of the pawl and ratchet mechanism, the cable 23 will be fed to draw the rug between the arms.

be interpreted as illustrative and not in a limited sense. It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language might be said to fall therebetween.
